3.3.1Paper feed components
The paper feed components include an ASF incorporating a friction separation system which uses a separation pad. Compared to previous ASF systems, it has a very strong paper feed force.
It consists of the following parts: Paper feed roller and separation pad, pressure roller and return corner, pressure plate, motor, and sensor.
Paper feed roller
(Transports

Pressure roller
(Applies pressure on
the paper on the separation pad to prevent transporting more than 1 sheet)
Separation pad
(Separates the paper)

Pressure plate
(Puts the next sheet
in position for the paper feed roller)
Return pawl
(Returns the paper
remaining on the separation pad)

The pressure roller and return corner prevent the paper that could not be completely separated by the separation pad from proceeding to the paper transport section. The pressure roller presses down the sheet of paper that is on the separation pad. It prevents multiple sheets from being transported. The paper therefore has a back tension (counteracting force against the feed roller's pulling force on the paper). Also, the return corner is for returning the paper remaining on the separation pad. The timing for returning the paper changes depending on the paper type and length selected with the printer driver.
